PATENT OFFICE.

LEVI TILL, OF SANDUSKY, OHIO IMPROVEMENT IN NUTS.

Specification forming part of Letters Patent No. 56,124. dated J ulv 3. 1866.

To all whom it may concern Be it known that I, LEVI TILL,of Sandusky, in the county of Erie and State of Ohio, have invented new and useful Improvements in Bolt-Nuts andI do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the ciently bending over the said flange in any proper manner .to cause it to so bind the washer placed upon the nut that, while it can freely turn, it cannot become detached, the advantages aiid fin'portance of which are obvious.

In accompanying plate the figure thereof is a side view of a screw-bolt with a-uut upon end in section, showing a washer applied to it, according to the present invention, and the bolt turned ofi' so as to allow the nut to be readily screwed thereon.

'A in the drawing represents a screw-bolt, made of any of the ordinary materials used therefor, and B a screw-nut screwed upon one end of the same. This not upon one of its faces,a, has a raised lip or flange, 1), around --tho1 pening in the not for receiving the screwbolt, and about this lip 1), upon the same face of the not, a washer, d, is placed, of any desired thickness, but exceeding ina greater or lesser degree the height of the said flange, which fiangei sthen, by means of a punch or any other suitable tool, upset or slightly bent over, so as to bear against and bind the washer to the nut-face, but yet leave it free to turn upon the nut, thereby, is -obvious,; so securing the washerto the nut that it cannot become detached therefrom, while at the same time it can act in the same manner and with the same client as washerssimply laid upon the face of the not over the bolt.

The advantages of securing a washer to' a screw-nut in the manner above explained are manifest to all, and therefore need no particular mention herein. r

In lieu of forming the raised flange or lip upon the nut-face around its opening through which the screw-bolt passes, it may be formed around the outer edge of the nut-face, and

then upset upon the washer; but I do notdeem it as desirable or advantageous as the manner above explained.

in order to facilitate the screwing of a nut upon a bolt, and to prevent injury to eithcrof their screw-threads, I turn oii the end of the bolt over which the nut is to be placed, as seen at y in the drawing, sufficiently to enable the nut to be centered before striking the screw-thread of the bolt, thus attaining the desired results, as is obvious without further explanation. 1 claim as new and desire to secure by Letters Patent- So securing a washer to a screw or other not that while it can freely turn on the face of the nut it cannot become disengaged therefrom, substantially in the manner described.
